I've asked several questions about my grey mare. She's the first grey I've ever owned and I'm always curious as to the stages she is going through. One constant I've noticed is the appearance of large oval "spots". Some of them stay permanently no matter her color change, and she's getting more and more of them with age. I looked it up and found that briefly listed Tetrarch Spots. Anyone else know anything about this or have grey horses with these Tetrarch spots?
